[policy changes improve market expectations of glass, soda ash futures soar]-Last trading week, glass and soda ash, which had been silent for a long time, sprang up in the futures market. By the close of trading on Friday, glass futures had achieved the limit that the market had not seen for a long time, and the price of soda ash futures also soared by more than 4%. Industry insiders believe that policy changes in the Qingdao property market have led to an improvement in market expectations and sentiment, and glass futures have emerged from a strong market, followed by a rise in soda ash; in the medium term, the demand for glass is expected to improve in the second half of the year, but it is not appropriate to start the expectation of the peak trading season prematurely, while the duration of the rebound of soda ash needs to examine whether more positive factors can be realized.
